Passage
Esron begot Aram, Aram begot Aminadab,
Esron begot Aram, Aram begot Aminadab,
Ruth 4:17 And the women, her neighbours, congratulating with her, and saying, There is a son born to Noemi, called his name Obed: he is the father of Isai, the father of David.
Ruth 4:18 These are the generations of Phares: Phares begot Esron,
Ruth 4:19 Esron begot Aram, Aram begot Aminadab,
Ruth 4:20 Aminadab begot Nahasson, Nahasson begot Salmon,
Ruth 4:21 Salmon begot Booz, Booz begot Obed,
The verse centers on "esron", "begot", "aram", and "aminadab". It is saying that the verse draws attention to "esron" and "begot", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 18's "These are the generations of Phares Phares..." into verse 20's "Aminadab begot Nahasson Nahasson begot Salmon...", so "esron" and "begot" belong inside that flow. In Ruth context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "esron" and "begot" with trust shaped by these words, not by a vague optimism outside the passage.
